Abstract: Transfer of private, sensitive or confidential data over WAN requires protection against eavesdropping, unautho- rized access, use, modification, perusal, disruption assuredly and efficiently. The available open-source utilities like Rsync reduces time and bandwidth required to update the file across the network. It uses the interactive protocols that detects the changes in a file and sends only changed data but it uses weak SSH encryption for secured transfer even over WAN. It is not a secure mode of the data transfer as there are well known attacks like brute-force attack, dictionary attack on SSH. Every Organization requires their data to be transferred securely and they rely heavily on tools which are secure and can be used efficiently without much constraints.
